This repository implements the C like language interpreter. The language consists of basic operations that make it Turing complete. Only int type variables are supported. Example of code:
n = ?; //console input
if (n <= 0){
print 0;
}
while (n > 0){
print n;
n = n - 1;
}Implemented check of syntax and variables definitions:
error_var = 3
var = 1;
error = 1 + - 2;
if (undef_var > 0){
print 3;
}Result:
syntax error, unexpected variable, expecting ; [2, 1]
var = 1;
^
syntax error, unexpected -, expecting ( or ? or number or variable [3, 13]
error = 1 + - 2;
~~~~~~~~~~~~^
identifier "undef_var" is undefined [5]For lexical analysis, Bison and Flex code generators are used. Files to generate are in ./bin.
To work with the abstract syntax tree, a request system is used. Description of this system located in ./src/frontend/headers.
Before building the program:
mkdir build
cd ./build
cmake .There are two build targets in the project:
make ParaCL
make Tests- ParaCL - build a program to work with ParaCL code
- Tests - buuld tests for interpreter
The command line arguments contain a file with the source text of the ParaCL language program.
